The Hidden is a 1987 science fiction thriller that stars Michael Nouri as Tom Beck, an LAPD detective investigating a series of robberies and murders perpetrated by seemingly innocent law-abiding citizens. Kyle Maclachlan co-stars as Lloyd Gallagher, an FBI agent who also is investigating the murders and who knows the true nature of the killer they are tracking.
The following weapons were used in the film The Hidden:
What appears to be a Steyr GB with under-barrel weaponlight attachment is seen in the arms dealer's firearms cache. This appears identical to another such pistol used in They Live.
Lieutenant Ed Flynn (Clu Gulager) draws his Smith & Wesson Model 36 snub when Gallagher crashes the press conference. Senator Holt (John McCann) takes it from him and fires it at Gallagher.
Smith & Wesson Model 10
Several LAPD officers in the film use Smith & Wesson Model 10 revolvers as their standard sidearms.
The snub version of the Colt Python is seen being fired by a member of the security detail that's protecting the Senator. One of the LAPD officers draws a 4-inch barreled Colt Python on Gallagher after he uses the flamethrower.

Micro Uzi
Several members of the security detail protecting the Senator carry the Micro Uzi pistol. It's seen being fired during the hotel shootout.

Shotguns
Mossberg 500 Bullpup
The Mossberg 500 Bullpup shotgun is the one of the weapons wielded by the alien when it takes over the body of Brenda Lee Van Buren (Claudia Christian).
